Premium quality raw materials.

End cap, mid pipe and intake tube and internal components are crafted of the highest grade SS304 stainless steel inside and out.

The Chrome Plated end cap is forged out of high quality brass. It features spark arrestor. This cap will never ever stain or lose its chrome gleam. (Frequent maintenance required.)

Why to install a spark arrestor?

Spark arrestors (also known as flame arresters) are designed for preventing the risk of fire because of the ignition of flammable materials, caused by spark emissions from the exhausts. The risk of fire caused by exhaust sparks is so high that access too many sites is barred unless engines are fitted with spark arrestors. Spark arrestors are most commonly used in conjunction with internal combustion engines as well as improving safety within fireplaces for instance. Often, a spark arrestor mimics a net fashioned from tightly interwoven wire gauze built to resist piece of ash, sparks, etc. Magnum Spark arrestor is sturdy and maintenance free, it will last as long as you own your exhaust. Our screen type spark arrestors integrated into BrutaliTune Exhaust cap, make these mufflers absolutely safe. H3Backfires in general/H3 Backfire, also called as lean misfire on deceleration is primarily attributed to an improperly adjusted or tuned engine, ignition or an exhaust / exhaust system with non-optimal gas restriction. If you are struggling with backfires, check your spark plugs and the ignition advance to verify the tune-up is correct. The plugs should be a light tan (deer brown) in color if worked properly. If all OK you should be suspicious the problem is at the exhaust. In many cases, misfire is an indication that the exhaust is too free flowing. Pipes might be too large in diameter or muffler's volume is higher than required for the engine configuration you have. BrutaliTune Exhaust installed on factory motorcycle does not produce backfires in case of appropriate restriction adjustment. Thanks to its variable-cross section core, you can tune that optimal power-band will fit your performance needs and riding style. Misfire is not uncommon on racing setups though, or on motorcycles run on extremely rich mixture at lower air / fuel ratio than 13:00.

brilliant invention

Bought it to my YZF R15. I knew perf tube pipes are loud, but was hoping with the accessory plate and suitable tune it would tone it down a bit. Actually it did however bear in mind this pipe is medium loud. Also, I was expecting it to be a bit lighter. Last complaint is the clamp they sent wasn't big enough. I fought for an hour to figure out how to fix the muffler. In other respects this is a brilliant invention. Tuneability delivered a very practical option to adjust the note and optimize the performance.

first choice for adjustable muffler

Magnum remained first choice for adjustable muffler that didnt exist in my earlier smoker riding years. Brutal is a bit overpriced beside to the laborious welding I am still impressed with the sound it produces and delighted with the horsepower it outputs.

noticeable increase in the lower RPM's.

As earlier reviewers have claimed, their weld-on is relatively easy to install and when compared to stock horses has a noticeable increase in the lower RPM's. It's fairly meaty sounding, and I am bound with loudest disk setup it broke the 100 decibel upper limit. Bottom line it well worth the money and I didn’t regret I forked over the money to buy this pipe.
